Long-term power minimization of dual-ν_Τ CMOS circuits

Abstract

In this paper, we define Long-Term power dissipation in which the effect of the system-level power management on the total power dissipation of a given circuit is considered. Then, we present a novel design methodology to minimize the Long-Term power dissipation of a circuit used along with dual-threshold voltage selection and voltage scaling. In simulation on 16-bit carry lookahead adders (CLAs), the proposed approach can reduce up to 80% and 25% of the total power dissipation along with clock- and power-gating, respectively.
